IMPROVEMET IN PROPELLING BOATS.

The Schedule referred to in these Letters Patent and making paxt of thesama.

To all whom it may concern:

Be it known that I, DANIEL J. Ross, of Havre de Grace, in the county ofHarford, and State of Maryland, hav`e invented a new and usefulImprovement in propelling-Boats; and Ido hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilledin' theart to make and use the same, referencebeing had t-o the accompanying drawings, forming part ofthisspecification.

This invention relates to a new and useful improvement in propellingboats through the water, more especially designed to be applied to smallboats, or those which are usually propelled by oars, and consists indriving a propeller-wheel at the stern of the boat, by

means of a cord and pulleys, by a crank or cranks,

4,turned by hand, as will be hereinafter more fully described.

.In 'the accompanying plate of drawings-v Figure l represents alongitudinal side view, with the side of the boat broken away, to showthe drivingapparatus.

Figure 2 is a top or plan view.

Similar letters of' referenceindicate corresponding arts.

A is the boat.

Bis a propeller-wheel, on the end of a shaft, C, which passes throughthe stern, after the manner of the ordinary propeller-wheel shaft. Y

D represents a pulley or baud-wheel on the propellershaft.

E E represent stands, which are properly fastened together, and varesupported on the bottom of the boat.

F is a crank-shaft, supported by the stands E, upon which (between thestands) there is another pulley or band-wheel, G, which standsat rightangles with the pulley D, as seen in tbe drawing. i

These pulleys lare grooved, and a round band is used, so that, althoughit makes a quarter turn, to

fit the position ofthe pulleys, there will be no danger of its runningof the pulleys.

H i's the operators seat. I is the driving-band.

` To propel the boat, the operator ori boatman takes l 'hold of thecranks J J, and revolves the pulleys G,

and the propeller-wheel, byineans ofthe band I.

This is a direct application of power tothe boat, and is much moresteady and etiectivc than when the' same power is applied by means ofoars.

K is the rudder.

L is the tillerbar, which is connected by means of cords m m, withfoot-levers n n, so that the` boatman, while he turns the cranks withhis hand,"

purposes set forth. l,

DANIEL J. ROSS. Witnesses:
